Description

Union all query over JSON data file fails when store.json.all_text_mode is set to false, and same query returns correct results when store.json.all_text_mode is set to true. Each JSON data file had only one type of object

{"key":<value>}

, and the values in each of the JSON data files were of same datatype. Test was executed on a 4 node cluster.

Query failed: RemoteRpcException: Failure while running fragment., For input string: "itzVxYBb" [ f1f81073-161c-4f24-89e5-37379413b01b on centos-04.qa.lab:31010 ]

Error: exception while executing query: Failure while executing query. (state=,code=0)

Then I set alter session set `store.json.all_text_mode`=true;

After setting son.all_text_mode to true, union all query returned correct results.

Resetting it back to false gives the same Exception
